Wireless fast charge refers to the wireless charging function, and has fast charging, you do not need to charge the data line, only need to put the phone near the wireless charger to charge.
Wireless fast charging is a combination of wireless charging technology and fast charging technology, and the mainstream models on the market now support wireless fast charging technology.
Wireless charging technology Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed.
The principle of fast charging of mobile phones is to increase the input value of the charging voltage or current. However, in order to truly realize fast charging of mobile phones, it also needs supporting circuits and hardware. The fast punch technology mainly includes Qualcomm's Quick Charge and Mediatek's Pump Express.
50w wireless fast charge is the charging power. In the \"Interim Provisions on Radio Management of Wireless Charging (Power Transmission) Equipment (Draft for Comment)\" (hereinafter referred to as the \"Interim Provisions\") published by the Ministry of Industry and Information Technology:
Since January 1, 2022, all mobile and portable wireless charging devices produced, imported and sold in China are required to have rated transmission power of less than 50W.
By next year, you may not see a wireless charging power more than 50W mobile phone.
